Abstract

Absolute ionization cross sections for the L subshells of Au by proton bombardment (0.25-5.2 MeV) have been determined from data obtained using a Si(Li) detector and the presently available values for radiative transition probabilities, fluorescence yields, and Coster-Kronig factors. The measured cross sections are compared with values calculated by Choi using the plane-wave Born approximation (PWBA) with either relativistic or nonrelativistic hydrogenic wave functions for the Au electrons. Except at low energies (ηLθL2
